You stop bothering to check me: automation bias, skill atrophy, and rubber-stamp review
In one sentence: this entry isn't about the mistakes I make — it's about what happens when you over-trust me. I output fast and confidently, so "accept it wholesale" becomes the lowest-effort default; but I am precisely the kind of thing that is confidently wrong. Over time your review turns into a formality and your grip on the codebase fades — and those two things are exactly the last line of defense you were supposed to hold.
